Legionella infections : a review of the literature and a prospective serological study of the incidence of Legionnaires disease at Groote Schuur HospitalDe Goveia, C 12 July 2017 (has links)
A prospective study of patients with pneumonia admitted to Groote Schuur Hospital took place over a one-year period in an attempt to assess the incidence of legionella pneumonia. Acute and convalescent serum samples were obtained from 113 patients. Eight patients (7,1%) showed a fourfold rise in antibody titre against Legionella pneumophila group 1 antigen by indirect immunofluorescent test (IFAT). The findings suggest that legionella pneumonia, although not common, should be considered in the aetiology of pneumonia at Groote Schuur Hospital. The results are presented and a review of the literature is undertaken.

Nutrient availability modulating physiology and pathogenicity of Legionella pneumophilaJames, Brian William January 1997 (has links)
A virulent strain of Legionella pneumophila serogroup 1 was established in continuous culture under defined iron-replete conditions at pH 6.9. Iron-limitation and extremes of pH (6.0 and 7.8) influenced the growth and metabolism of L. pneumophila, as manifested by increased metabolic activity, impaired energy coupling, and altered metabolic fluxes. In particular, the physiological versatility of L. pneumophila was demonstrated by a significant decrease in the iron content of biomass (6-fold increase in Yiron), coupled with reduced metabolic efficiency (Y, on), in response to iron-limited growth. Iron limitation promoted the accumulation of significant intracellular reserves of poly- ß-hydroxybutyrate (16 % cell dry wt.), which supported long-term survival of L. pneumophila under starvation conditions. Expression of the important pathogenicity factor, the zinc metalloprotease, was regulated by iron availability. Common iron acquisition mechanisms, such as siderophores and transferrin receptors, were not elaborated by iron-limited cells. However, human transferrin was identified as a potential iron source for L. pneumophila, with the zinc metalloprotease mediating transferrin digestion and possibly iron acquisition. Iron-limitation and extremes of pH also influenced cellular morphology and the surface properties of L. pneumophila, promoting the formation of uniform cultures of short rod-shaped bacteria, with altered fatty acid, phospholipid and protein composition. In addition to morphological and physiological adaptation, iron limitation had a significant effect on the virulence of L. pneumophila. Iron-replete cells grown at pH 6.9 and 6.0 were highly virulent in a guinea pig model. However, the virulence of L. pneumophila was significantly attenuated (P < 0.05) in response to iron-limited growth. This phenomenon was reversible, and correlated with reduced phagocytosis and / or reduced intracellular survival following infection. Decreasing the pH of iron-limited cultures to 6.0 did not stimulate recovery of culture virulence. Therefore, this study clearly demonstrates that environmental stresses, including iron limitation and extremes of pH, play an important role in modulating the physiology and virulence of L. pneumophila, inducing the expression of distinct phenotypes differing in their ability to persist in nature and cause infection.

Interaction of Legionella Pneumophila and Selected Algae and Response to DisinfectantsKo, Chi-mei 12 1900 (has links)
Two species of cyanobacteria (Fischeralla sp. 29161 and Phormidium autumnale) and one species of green algae (Fritschiella tuberosa) were found to promote survival of Legionella pneumophila in mineral salts medium cocultures. During the early stage of incubation Fischerella sp. supported growth of Legionella pneumophila even though the bacteria would not grow in the algae-free basal medium.
